844 | Say Y here to include experimental MMCIF loading code in | |
845 | romImage. With this enabled it is possible to write the romImage | |
846 | kernel image to an MMC card and boot the kernel straight from | |
847 | the reset vector. At reset the processor Mask ROM will load the | |
848 | first part of the romImage which in turn loads the rest the kernel | |
849 | image to RAM using the MMCIF hardware block. | |

890 | The Maple Bus is SEGA's serial communication bus for peripherals | |
891 | on the Dreamcast. Without this bus support you won't be able to | |
892 | get your Dreamcast keyboard etc to work, so most users | |
